You have to take an eyesight test before you start practical test.

In good daylight you should be able to read a vehicle number plate with letters 79,4 mm (3,1 inches) high at a minimum distance of 20 meters (about 67 feet).

If you need glasses or contact lences to read the number plate, that's fine. You must wear them while driving.

​At the start of your practical driving test you have to correctly read a number plate on a parked vehicle.

If you can’t, you’ll fail your driving test and the test won’t continue. DVLA will be told and your licence will be revoked.

When you reapply for your driving licence, DVLA will ask you to have an eyesight test with DVSA. This will be at a driving test centre. If you’re successful, you’ll still have to pass the DVSA standard eyesight test at your next practical driving test.

The legal alcohol limit for drivers is:
- 80 milligrams of alcohol per 100 millilitres of blood, or
- 35 micrograms of alcohol per 100 millilitres of breath, or
- 107 milligrams of alcohol per 100 millilitres of urine

Even small amounts of alcohol can affect your ability to drive.

If the police want to investigate whether you are over the drink driving limit, they will carry out a screening breath test at the roadside. If you fail this test, or if they have other grounds to believe that your driving was impaired through drink, you will be arrested and taken to a police station.

Anyone caught over the legal alcohol limit when driving will be banned from driving for at least 12 months, and fined up to £5,000. You can also be sent to prison for up to six months. Imprisonment, the period of disqualification and size of fine depend on the seriousness of the offence.

If you are caught drink driving second time in a 10 year period, you’ll be banned for at least three years.

Only ADIs and trainee licence-holders can teach to drive for payment. They must display a badge on the windscreen during lessons. An ADI displays a green badge on the windscreen, and a trainee driving instructor displays a pink badge.

You must have a provisional driving licence when you’re learning to drive.

If you practise your driving with friends and relatives  (without paying them) they must:

- be over 21
- have had their driving licence for 3 years
- be qualified to drive the type of vehicle you want to learn in

You can be fined up to £1,000 and get 3 to 6 penalty points on your provisional licence if you drive without the right supervision.

If a traffic accident occurs and you are driving, then you need to assess the situation and see if any of the following situations apply:
- Is anyone injured?
- Has there been any damage caused to someone else's property, or another vehicle?
- Has an animal been killed or injured (an animal applies to a dog, pig, goat, sheep, ass, mule, horse or cattle).

If any of the above points do apply, you are required to stop at the scene and remain there for a reasonable period of time that will allow any other people involved directly or not in the accident to come to you and request your contact details.

If you are driving someone else's car, then you must supply the contact details of the registered owner too.
 
If you don’t leave your details at the scene, then you must report the incident to a police officer as soon as is practically possible (within 24 hours). You can ring to advise the police station, but it is not acceptable to report the incident over the telephone – it must be done in person.

The supervising driver must:

- be at least 21 years old
- held a full driving licence for a minimum of 3 years
- meet the minimum eyesight standards
- ensure the car is in a safe and legal condition
- ensure the car displays red L Plates (or D Plates in Wales) if a learner is driving
- car insurance must cover a learner driver
